Tips for inserting background music in PPT

PowerPoint can insert CD music, Wav,midi and MP3 files, and audio narration into your slides, but when you insert a background music with these methods, a small disc or horn icon appears, although it can be hidden while playing, but it is often an eyesore in the editing state. And in addition to recording methods, other ways not to actually insert the music content into PowerPoint, if the copy or packaging missed the music file, on the other computer can not put out the sound.
For ordinary slides with background music, use this method.
Select the first slide, choose slide transitions under the Slide Show menu, select Other sounds in the sound column, and then add a sound file. Here is the only thing to add WAV format files. Then tick before the "loop playback to the next sound starts" option. Click "Apply".
